У меня есть ошибка для редактирования с hibernate + spring. Я уже ищу в этом. Но до сих пор не удается найти решение. Я пишу код C R U D, все работают нормально, как добавление/удаление, но я получаю ошибки при редактировании/обновлении базы данных.hibernate get id = 0 Пакетное обновление возвращает неожиданный счетчик строк из обновления [0]; фактическое количество строк: 0; ожидается: 1
Просьба помочь вам найти решение?
Спасибо.
Вот мой код:
модальный/организация EmployeStatus.java
@Entity
@Table
public class EmployeeStatus {
@Id
@Column
@GeneratedValue(strategy= GenerationType.AUTO)
private int id;
@Column
private String name;
public EmployeeStatus() {
}
public EmployeeStatus(int id, String name) {
super();
this.id = id;
this.name = name;
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
@Override
public String toString() {
return "EmployeeStatus [id=" + id + ", name=" + name + "]";
}
}
Dao осущ EmployeeStatusDaoImpl.java

}

session.persist(es);

//session.update(es);

sessionFactory.getCurrentSession().flush();

logger.info("Employee Status updated successfully, Employee Status Details="+es);
}
